project I'm using Visual Studio. But when I need to work on linux I run emacs. (also I don't like qt at all)
Also (mostly because I like last.fm plugin and clojure support there) I found an nice IDE for … linux (still tryeng to switch to emacs from it ==' for some reasons) IDEA, not I recommend to use it for C++ but maybe it's not bad too so you can add it to your list.
